The replica of silicone mold which can produce the test samples and the market-displayable products without making expensive metallic patterns is advantageous because it incurs less cost than the ordinary method that manufactures the products from the metallic patterns. However, the production of the products using silicone mold should require a technician with professional knowledge about the metallic patterns every time. Thus we tried to judge whether a forming analysis software for iron molding can be applied to silicon molding in this paper. In other words, this paper suggests a method to use a computer simulator from the designing step of the silicone mold, which is the most important part in making replica using simple silicone molds to the step of pouring the cast. The paper shows that if the know-how of a professional worker is provided in advance, an amateur worker can easily produce silicone molds of the best quality, the defective rate of the products will be decreased, and the replica will have a more complete status. By doing so, we suggested a possibility for reducing the delivery time at the production sites and for improving the product quality.

The purpose of the study is to establish a concept of property development planning process and factors by analyzing the several case studies, which prior proposed the highest and best use development of property. The value of property is dependent on the circumstances and the timing. Real property development is essential to develop in the highest and the best. The prior concepts of the highest and best use focused on the real estate appraisal, but these studies aroused an interest that related the highest and best use concept as a determinant of property development. As a results, this study suggests the process and the check points of property development planning phase. The first step is having a thorough grasp of the status of property. The Second step is the circumstantial analysis including legal restriction, locational environment, real estate market and economic conditions. The next step is, in accordance with these analysis, setting up the development concept and alternatives. Through the feasibility studies, we can make a choice the highest and best use development plan. In these days, the importance of development strategies such as design exceptionality and plan management are increased. Therefore, the integrated plan for the property development is very important.

In recent years, manufacturers of animal-based foods with health claims have encountered difficulties in the labeling of their products because of a lack of regulation on defining the functionality of animal-based foods. Therefore, this study was conducted to establish the basic requirements for the development of a definition for functional animal-based foods by investigating consumer and industry awareness. Survey data were collected from 114 industry representatives and 1,100 consumers. The questions of the survey included items on production status and future production plans, functionality labeling, promotion plans, establishment of definition, the role of the government, consumer perception, and selection of products. The results show that both industry representatives and consumers believe that legislation and the provision of scientific evidence should be improved for the development of a functional animal-based foods market. The results obtained from this study will contribute to consumer trust by supplying correct information and can be utilized in the industry as basic data for the development of functional animal-based food products.

Google Android provides market based application distribution to provide ease use of application services. While openness of Android allows various ways of application distribution, including installation of unsigned application. such openness also invokes critical threats such as the spread of malwares and the illegal distribution of applications. In order to prevent such threats, several distributors use on-line authentication techniques by using mobile subscriber's information. However such methods also have limits that even legal users cannot use their purchased application in situations. Therefore, in this paper, we discuss such problems and provide some ideas of authentication method that allow users to use their purchased application when users change their status.

Power electronics is an interdisciplinary area that is interstitial to all of the major disciplines of electrical engineering including power, electronics and control. Today, the covering field of power electronics has more widely spread out with the help of ever evolving microelectronics and computer science. Whereas, in Japan the tendency is becoming remarkable nowadays that science, especially "mathematics" and "hardware work", are falling into disfavor with the young people. For these reasons, it has become a very important problem to find out "what are the truest essentials of power electronics\ulcorner" and "How to give students incentives to learn power electronics\ulcorner " from an educational point of view In under-graduate and graduate courses in universities. On the other hand, the power electronics engineers in companies are always required to comply with the ever changing trend of global and open market. However, it takes long time to cultivate their skills. Against the background, "The Cooperative Research Committee on Education of Power Electronics" was established in the IEEJ Industry Applications Society during 2000-2001. The present status of the power electronics education in Japan is surveyed in this paper, and some problems with remedy are pointed out based on the discussions performed in the committee.sed on the discussions performed in the committee.

Because PBD was started as a design tool for steel construction and concrete construction, it was able to applied to the post and beam method of wooden building constructions. But, it may not suitable to light frame wooden construction that is becoming popular in domestic construction market due to the economical efficiency and the constructive simplification. Owing to the share effects between member and sheathing material or among structural members, light frame wooden construction is different from post and beam construction that use a single structural member. Therefore, consideration on the system analysis and system design are urgently needed to use in actual life and inspect the reliability of structures from the system view. With this in mind, code conversion from ASD to PBD that is pressing issue in domestic wooden building construction was studied, also various countries status about PBD were considered and then approaching methods on the system reliability were referred. Finally, several considerations for the development of PBD were explored. PBD should be considered as, not only a new structural design process that select sizes of structural member, but a industrial tool that can lead a development of more reliable wood products. A strongest point of PBD is independent of various construction materials and construction types.

The purpose of this study was to segment consumers based on sales promotion orientation and examine the differences between the consumer segments on shopping styles and demographics. A total of 462 responses collected from a questionnaire survey to subjects aged over 20 were analyzed. Cluster analysis on sales promotion orientation identified four groups including rational group(21%), active group(28%), insensitive group(22.1%), and interest group(28.9%) of sales promotion. MANOVA, ANOVA and $\chi$$^2$-test revealed significant differences among the four groups on shopping styles(high-quality prone, value prone, price prone. brand prone, fashion prone, hedonic shopping prone, and loyalty) and 4 demographic characteristics(i.e., age, marital status. occupation, and education). The rational group showed lower brand proneness than did other groups while the active group showed higher price and brand proneness. The interest group showed high value, brand, and hedonic shopping proneness while the insensitive group was the least engaged in shopping styles. The study developed a profile of each segment and provided marketing implications.

As mentioned in Part I all groupware products have been categorized into three areas which include cooperation/document management systems(CMS), collaborative writing systems(CWS), and decision-making/meeting system(DMS). This study deals with a comparative analysis of the last two areas, which is added to the first. It turns out that DMS has a higher market share than CWS. However. since effective collaboration requires the functions inherent to these two systems. they should be integrated somehow. The systems' functions that have been implemented in response to design issues have been described. Each group of the functions has been divided into three parts which consist of basic function, quasi-basic function. and others. Such a decision has been made according to the frequency rate of the functions provided in the products. While the basic functions in CWS include collaboraive writing beyond restriction of time and place, group awareness. version control. and others, in DMS realtime collaboration. brainstorming. presentation. various task support. policy formation. document management, multimedia, subgroup communication. topic commenter, categorizer, screen capture and various rile transfer. The basic functions are merged into the integrated functional model which was proposed in Part I. Since the model is so flexible that it can partially include the quasi-functions in addition to the hasic functions. a large number of products may stem from the modification of the functional model.
